Construction
of New Water Pumping Station Requires Westra Construction Corporation, Palmetto FL, is three months into an eighteen-month project, building a new water pumping station for the Tampa Bay Water Supply Co. We spoke to Jeff McWhorter, Westra President, and his men in the field: Larry King, Project Manager, and Brian Beukema. New construction will include an intake structure at the Alafia River, an underground pipeline running approximately 1500 ft., and a pump station building. The intake structure includes a screen system for removal of large leaves and debris. Once through the filter, the water will pass through 42 in. diameter steel pipes to the pump station. Because it is a gravity-feed system, the pipes are being laid well below river level. Westra is breaking through 15 ft. of hard limestone approximately 10 ft. below water level. During construction, the Alafia is being held back by a fabric porta-dam stretched between steel braces. Sections of the work area for the pipeline are as close as 6 ft. from the dam. The
Power and Reliability of the V55 This is thanks, in part, to Tramac’s patented TPS Tool Protection System, standard on most Heavy Range breakers. The specially-engineered front guide, oversized bushings, and tool and retainer pins allow the strongest points to take the stress—tools and wear parts last longer.
Another advantage of the V55 is the precise control it gives the operator over just how much rock is broken and removed…an important economic consideration on this project, since whatever is removed must be replaced by flowable fill. McWhorter chose the V55 because he wanted the local support of Linder Industrial Machinery, Plant City FL, represented by Lance Carmen and Dave Teemey. He also wanted a breaker he could rely on for consistent high performance, and he had long been aware of Tramac’s reputation for quality equipment. Larry King mentioned the ease of day-to-day maintenance due largely to the fact that the V55’s operation is fully hydraulic. Its piston is both lifted and driven hydraulically. Competitors’ breakers lift the piston hydraulically but drive it down with pressurized nitrogen. The nitrogen charge tends to leak off, lessening production and eventually requiring a recharge. Tramac’s system eliminates these problems.
